Heavy Rain Hits the City
On July 19, 2026, a sudden, extreme downpour once again put Shanghai to a severe test against urban waterlogging. That afternoon, strong thunderstorm clouds swept over the city. The observation station in Wujiaochang, Yangpu District, recorded a cumulative rainfall of 212.8 mm, with a maximum 1-hour rainfall of 104.5 mm, reaching the level of a “super-heavy rainstorm” over 24 hours. Among the city’s 662 rainfall monitoring stations, 3 reached the super-heavy rainstorm level, and 20 reached the heavy rainstorm level. Orange warnings for heavy rain, yellow warnings for hail, strong winds, and lightning were issued in succession, and the extreme weather instantly turned the city into a “sea-viewing mode.”
Urban waterlogging: prevention is better than emergency response. The key to “prevention” lies in “being able to see it, measure it accurately, and report it quickly.” The shortcomings of the traditional flood control model—relying on manual inspections and post-disaster emergency response—are prominent: dangers are only discovered after water has accumulated, missing the window for proactive measures; 24/7 monitoring of locations like underpasses, low-lying roads, underground garages, and manholes is impossible; and delayed warning transmission means a lack of real-time data to support pumping station scheduling, traffic control, and personnel evacuation. Faced with extreme weather like heavy rain, a smart waterlogging monitoring system with proactive warnings and comprehensive awareness has become a core necessity for building a resilient city.
Leveraging its independent R&D capabilities and smart water management cases across the country, Meokon Sensing has launched an urban waterlogging safety monitoring solution. Centered on the “Waterlogging All-in-One Machine,” it provides 24/7 water level monitoring and early warning for scenarios such as underground garages, underpasses, depressed roads, and low-lying areas.
01 Waterlogging All-in-One Machine: An Intelligent Monitoring Terminal Adapted for Urban Flood Control Scenarios
The MD-K986 Waterlogging All-in-One Machine is a professional, intelligent water level monitoring terminal adapted for urban flood control scenarios, meeting the SL651-2014 standard for hydrological monitoring data communication. Its core advantages are as follows:
- Dual Detection, Precise and Reliable: Integrates dual technologies of water immersion contact sensing and hydrostatic level measurement. It triggers an alarm when the water level reaches 1cm (e.g., slight water accumulation in a garage) and accurately measures depths from 8cm to 5m (e.g., deep water in a tunnel), achieving full coverage from “trace accumulation” to “deep waterlogging.”
- Wireless Transmission, Real-time Online: Supports 4G/NB wireless communication and is equipped with an external antenna, adapting to various network environments to ensure stable data transmission.
- Ultra-long Battery Life, Low Maintenance Cost: Battery-powered with a minimum 3-year lifespan. An optional solar power module can be configured to significantly reduce operation and maintenance costs.
- Intelligent Alarm, Graded Response: Automatically pushes alerts for water level exceedance, device tilt, and low battery to the management platform, enabling graded alarms and rapid response.
- IP68 Protection, Fearless of Harsh Environments: Can operate stably in environments from -30°C to 70°C, is waterproof and dustproof, and adapts to harsh outdoor conditions.
02 Device Management Platform: From “Passive Emergency Response” to “Proactive Prevention”
Supported by the “DLM” (Big Lazy Cat) Device Health Management Cloud Platform, it centrally manages various intelligent sensor terminals distributed across city-wide flood-prone points like underpasses, underground garages, municipal pipe networks, and river pumping stations. It provides operation and maintenance functions such as on-site Bluetooth debugging, remote fault diagnosis, device battery life analysis, low-battery alerts, and graded warning push notifications, realizing digital, unified management of urban flood control facilities and rapid response to dangerous situations.
03 Previous Project Case: Siyang County Urban Lifeline Safety Engineering Project
Flood-Prone Point Monitoring
This project is the first phase of the drainage special project for Siyang County’s Urban Lifeline Safety Engineering. Following the local “7+1″ comprehensive safety monitoring construction framework, MD-K986 Waterlogging All-in-One Machines were deployed at multiple key flood-prone road sections in the urban area to monitor regional waterlogging and accumulation. The monitoring data is uniformly integrated into the Siyang Urban Lifeline Supervision Platform, which can accurately identify waterlogging risks and provide timely warning information for drainage scheduling, effectively enhancing the county’s emergency response capability for waterlogging.
